P: Lightroom Classic: Editing raw file in PS from LR loses profile

Hello, i have the same problem with Lightroom 10 and Photoshop 2021.
I tried Johan's method but it only worked when i keep photoshop open and only if i use the same custom camera profile on other photos.

When i change to other profile or close and reopen photoshop, it happen again (even with the same photo and custom camera profile).

Just following up to report that the problem has remained resolved after using Johan's suggestion one time.

@arjun_haarith Note that the problem went completely away once I used Johan's suggestion once.  In subsequent invocations, I was able to open the CR3 files from Lightroom normally in Photoshop and the custom profile was there.  

Yes I was.  I have the Canon R5 and Adobe does not have any camera specific color profiles available (hint, hint...).  I was using custom profiles to make up for that gap.

Hi,

Were you using any custom camera profile ? 

Thanks,
Arjun

The reason i don't have autowrite on is because i frequently select 10's or 100's of images and then repeatedly make batch corrections on a set, and i find that with autowrite on, it slows down my process. I prefer to select all and CMD+S at the completion of a project to generate and then move all of the small xmp's to my servers.

From the Color Fidelity maker Colin, It's his understanding that Adobe is aware of this issue and it will be fixed in the next update.

Best to export a DNG with all edits AND profile so other's can test. I don't have such a document on this end to see what might be going on. 

Why do you not have auto-write XMP on? 

Hi Andrew, thanks for your comments, but unfortunately i'm way ahead of these first steps. Tried all of the above, disabling the GPU on both LR and PS, verifying, remaking v2 profiles (v4 doesnt really play nicely in all circumstances) etc, etc. 

It is indeed a bug in LR. You can solve/test the issue by ENABLING auto write changes to xmp files. That somehow solves the issue for the time being. The maker of the Color Fidelity Profiles got back to me that another user figured out the workaround.

Desaturated with ProPhoto RGB sounds like at least in PS, color management is off and maybe it's your display profile. 

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.

working space is ProPhoto, and preserve for all. To be clear, this only happens with R5 files with CF profiles in LR, does not happen with Adobe Color, or any other file/profile combination.
